LPC55S69 : 1-bit SPI NOR FLASH support

[EugeneHiihtaja]

Hello !

In UM mentioned about NOR flash memory support in ROM code directly :

8.6.11.2 1-bit SPI NOR FLASH support (for version 1B only)   and it can be programmed by using blhost.

But it is not clear to what SPI interface it can be connected and how to initialize it  ( if need ).

What about ROM api what use used for work with SB file ?

Can they work directly with this NOR memory ?

Regards,

Eugene

Hi, Eugene,

I have to admit that the part in UM11126.pdf is confused and unclear, I have asked AE team, I will give you a reply after I get a feedback.

Hi, Eugene,

I get feedback from AE team, the FlexComm3 module is used as single I/O SPI NOR flash interface as the following fig.

Hope it can help you
